The Walking City was an idea proposed by British architect Ron Herron in 1964. Ron Herron proposed building massive mobile robotic structures, that could freely roam the world, moving to wherever their resources or manufacturing abilities were needed. Various walking cities could interconnect with each other to form larger 'walking metropolises' when needed.
Halley Research Station, run by the British Antarctic Survey, is located on the Brunt Ice Shelf floating on the Weddell Sea in Antarctica. It is a structure which is jacked up on legs to keep it above the accumulation of snow. There are skis on the bottom of these legs which allows the building to be relocated periodically. It is a string of 8 modules, each on stilts with skis.
